FIELD CROPS. 



Experiments with crimson clover to study the influence of 



time of seedina; (^'e;r Jersey Sta.s. lipt. JSIf',, jijk ]1<j-121., pis. fi). 



Ciimsoii clover seed was sown at the station on a heavy clay loam 

 August 4, 13, 29, and October 1, and on a farm near jMoorestown, New 

 Jersey, on a coarse sand to sandy loam July 11, 21, August 4, 18, Sep- 

 tember 14, 20, 21, 22, 29, October 4 and 23^ The weather during the 

 fall was dry and hot. Cuts arc giveu of specimen ])lants of different 

 sowings. In the cooperative test the sowings of August 4 harrowed 

 in on pea vines turned under, and of August 18 harrowed in among late 

 tomatoes, were most satisfactory. The experimenter states that in the 

 latest sowings a large percentage, perhaps a majority, of the ])lants had 

 stems devoid of branches. 



Experiments with corn, 1896, J. F. Duggak {Alahama ('<>llef/e 

 8t<(. Bill. Tj, ]>}). 3f!l-oS::J). — Owing to drought the yields were light in 

 all experiments of the year on uj)land soil. 



Fourteen varieties were tested, and a table shows for each variety 

 the number of pounds of thoroughly dry unshucked corn required for 

 o(! lbs. of shelled corn, the ])ercentage of grain in the unshucked <;orn, 

 and the yield per acre of shelled corn. St. Charles (a white variety), 

 Early ^Mastodon, and Blount Prolific gave the best yields — 25,1, 22.7, 

 and 22.3 bu, per acre, respectively, A table shows comparative i)ro- 

 ductiveness of 39 varieties tested from 5 to 20 times in the Southern 

 States, the leading varieties being Cocke Prolific, Mosby Prolific, Cal- 

 houn Ked Cob, St. Charles, and iMammoth White Sui'prisc. The 8 

 southern varieties averaged 17.2 bu. jter acre and the (J northern varie- 

 ties 21 bu., and in a coraiiarative test of seed from different latitudes 

 both varieties used gave slightly larger retuins with seed fiom Illinois 

 than from southern -grown seed. The detailed results are tabulated 

 for an experiracMit on ninth-acre plats to test the use of kernels from 

 different i)arts of the ear as seed, and a summary is giveu of similar 

 experiments at other stations. 



The differences in yield were very small. IJutt kernels from 4 ears 

 produced an average yield of 2,439 grains of corn T>cr plant, tip kernels 

 2,187 grains, and middle kernels 2,092 grains. The compiled results 

 agree with those of the year's experiment at Ihe station in placing butt 

 kernels first, ti]) keinels secoml, and middle kernels fliird in produc- 

 tiveness.
